ASP.net parsing Diffgrams in XML to use in DataList - asp.net

Question

I have a method:
public static DataSet getTable()
{
DataSet DS = new DataSet("My Set");
DS.ReadXml(getCategories());
return DS;
}
My getCategories() returns a stream containing my XML.
But when I run this, I get this error:
The supplied xml instance is a schema or contains an inline schema. This class cannot infer a schema for a schema.
So I'm not sure what to do.
My goal is to use the call to getTable() to populate a DataList.
I've tried using the DataTable and I get a different, but similar error.
Any help would be great.
Thanks.
Here is my XML file. Might help. Thanks.

It is related to the fact that you have the following xml in there.. If you take that out it should work. it is not going to create a schema for something that already exists.
<xs:element name="Category">
<xs:complexType>
<xs:sequence>
<xs:element name="PartCategories" type="xs:string" minOccurs="0" />
<xs:element name="CategoryDescriptions" type="xs:string" minOccurs="0" />
<xs:element name="CategoryImageURLs" type="xs:string" minOccurs="0" />
<xs:element name="CategoryModelFlags" type="xs:string" minOccurs="0" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:choice>
</xs:complexType>
</xs:element>
</xs:schema>
